Question on GMC Envoy brake light problem?
We have a 2005 Envoy that the left, right, and top center brake lights do not work. All fuses, bulbs, bulb socket boards, brake pedal switch, and ground wire cleaning have been replaced. All other Lights work. Plugged in a 24' car hauler into the trailer connection and had brake lights on the trailer, but not the Envoy. I'm stumped here. Any ideas or suggestions?

Are the brake and turn signal bulbs the same? If so then the most likely culprit is the turn signal switch. If it has separate turn bulbs then you have a wiring break somewhere between the brake light switch and the bulbs.

Go to the dealer and they will do pin tests to find the problem.It's cheaper than a DUI
